I think a lot of people don’t realize just how extensive maintenance checks on airplanes are. They’re not just “checking” to see if anything is wrong, but rather basically taking apart most of the plane and then putting it back together. That’s why you shouldn’t feel unsafe when you’re flying an older plane — it still undergoes the same maintenance checks of newer planes, as it’s basically taken apart and put back together every few years.
So it’s pretty cool that Emirates created a sub-two minute video giving an overview of the process:
Pretty impressive, eh?
